U-space Contingency Management Service: Enhancing U-space Volumes Safety

This work proposes an advanced U-space contingency
management based on a new U-space strategic service that
enhances mission description with a set of alternatives vertiports
to be occupied in case of contingency. The new service, closely
linked to demand-capacity balance and strategic deconfliction
services, assigns safe alternative landing spots by analyzing the
planned missions. Two potential solutions are outlined, primarily
distinguished by the number of contingency vertiports assigned:
contingency management based on assigning a single alternative
vertiport to each mission (static) or assigning multiple contingency
vertiports that are valid during specific time intervals. It is
demonstrated that this improved mission planning can ensure that
U-space volumes operate under ultra-safe conditions when
encountering unforeseen events, highlighting its importance in
high-risk scenarios such as urban air mobility deployments.
